why do we blink? Does the number of times we blink vary?

Question

Why do we blink? how many times do we blink and does the number vary from person to person?

Answer 1

Blinking relieves the strain eyes are exposed to. Cells on the retina have to process signals the whole day, if you blink it has the same effect for them as would a 5 minutes break every 30 minutes help you during your work. Moreover, eye lids help to moisten the eyes. wet eye is necessary to have the surface of the eye smooth and to relieve the strain as well. It has the same effect as the shower on your body. And at last... blinking help to wipe dust that keeps falling onto the eyes.

Answer 2

Blinking helps rehydrate the eye. It washes away any kind of dirt or just anything that gets in your eyes. I dont think anyone blinks the same amount of times in an hour lol

Answer 3

Blinking, as opposed to batting, our eyes automatically supplies two forms of moisture to our eyes, to keep them from drying out, and to keep foreign matter from entering and irritating our eyes.



The average person blinks 25 times per minute, which works out to 13,140,00 blinks per year.

Answer 4

we blink cause we tend to protect our eyes all the time from any potential harm, and also, we blink to moisturize our eyes either with tears or this kind of lubricant the eyes secrete.



blinking is controlled by the blinking center and is often affected by external stimulus

Answer 5

we blink so that our eyes become lubricated, other-wise the eyes become very stiff!!!!

the tear gland in our eye produces the liquid which lubricates our eyes!

on average people blink 16 times per minute

in 24 Hour day we blink 23040 times!!

and yes it can vary from person to person!!!!!!!!!!!!!!
